Algebraic geometry is a branch of .....?
Correct Answer
A. Mathematics
Explanation
Algebraic geometry is a branch of mathematics that combines algebraic techniques with geometric concepts to study the properties of geometric objects defined by polynomial equations. It involves the study of algebraic varieties, which are sets of solutions to polynomial equations, and their geometric properties. By using algebraic methods, algebraic geometry provides a powerful tool for understanding and analyzing geometric objects in a rigorous and systematic way.
2.
. Examples of the most studied classes of algebraic varieties are the following except .....
Correct Answer
B. Point
Explanation
The given question asks for the exception among the most studied classes of algebraic varieties. The options include lines, circles, hyperbolas, and points. Lines, circles, and hyperbolas are all examples of algebraic varieties as they can be described by algebraic equations. However, points are not considered as algebraic varieties since they do not have any dimension or can be described by algebraic equations. Therefore, the correct answer is "Point."
3.
In what century did algebraic geometry split into several subareas?
Correct Answer
A. 20th
Explanation
Algebraic geometry split into several subareas in the 20th century. This splitting occurred as mathematicians began to explore different aspects and applications of algebraic geometry, leading to the development of subfields such as commutative algebra, algebraic topology, and algebraic number theory. The 20th century was a period of significant advancements in mathematics, and algebraic geometry played a crucial role in these developments.
4.
In the 20th century, algebraic geometry split into how many subareas?
Correct Answer
A. 5
Explanation
In the 20th century, algebraic geometry split into five subareas. This means that the field of algebraic geometry branched out and diversified into different specialized areas of study. The splitting of algebraic geometry into multiple subareas allowed for more focused research and exploration of different aspects within the field.
5.
Some of the roots of algebraic geometry date back to the work of the Hellenistic Greeks from the .... century BC.
Correct Answer
C. 5th
Explanation
The correct answer is 5th. Algebraic geometry has its roots in the work of the Hellenistic Greeks from the 5th century BC. This means that the study and development of algebraic geometry can be traced back to this time period and the contributions made by the Hellenistic Greeks.
6.
The ...... were able to solve by purely algebraic means certain cubic equations, and then to interpret the results geometrically.
Correct Answer
B. Arab mathematicians
Explanation
Arab mathematicians were able to solve certain cubic equations using algebraic methods and then interpret the results geometrically. This suggests that they had a deep understanding of both algebra and geometry, allowing them to bridge the gap between the two disciplines. Their contributions in this area were significant and helped advance the field of mathematics.
7.
The geometrical approach to construction problems, rather than the algebraic one, was favored by most ......... century mathematicians.
Correct Answer
A. 16th and 17th
Explanation
During the 16th and 17th centuries, mathematicians preferred a geometrical approach to construction problems over an algebraic one. This means that they relied more on visual representations and geometric principles to solve mathematical problems, rather than using equations and formulas. This approach was likely influenced by the advancements in geometry made during this time period, such as the development of analytic geometry by RenĂ© Descartes. The emphasis on geometry in the 16th and 17th centuries eventually gave way to a stronger focus on algebra in later centuries.
8.
Who revolutionized the conventional way of thinking about construction problems through the introduction of coordinate geometry?
Correct Answer
A. The French
Explanation
The French revolutionized the conventional way of thinking about construction problems through the introduction of coordinate geometry. This mathematical system enabled them to represent points, lines, and shapes using numerical coordinates, allowing for precise calculations and measurements in construction. The French mathematicians and engineers used this innovative approach to solve complex construction problems and improve the accuracy and efficiency of their designs.
9.
Most of the algebraic character of coordinate geometry was subsumed by the of .......?
Correct Answer
A. 18th century
Explanation
In the 18th century, the field of coordinate geometry developed significantly. This branch of mathematics combines algebra and geometry, allowing for the study of geometric shapes using algebraic equations. The work of mathematicians like RenĂ© Descartes and Pierre de Fermat during this time period laid the foundation for coordinate geometry, introducing concepts such as the Cartesian coordinate system. Therefore, the correct answer is 18th century.
10.
Algebraic geometry can only be taught in a ........ class?
Correct Answer
C. Mathematics
Explanation
Algebraic geometry is a branch of mathematics that combines algebraic and geometric concepts to study geometric objects defined by polynomial equations. It involves the study of algebraic varieties, which are solutions to systems of polynomial equations. Therefore, it can only be taught in a mathematics class, as it requires a strong foundation in mathematical concepts such as algebra and geometry.
